n, QUAKTERLY JoURNAL OP SciENCE. 



IN the January number of this Journal there is an interesting paper 

 hy Mr. R. E. Alison on the Peak of Teneriffe, which notices 

 some of the volcanic phenomena of the Island ; it is illustrated by 

 two chromo-lithographs. There is also a note by Prof. Ramsay on 

 the recurrence of species in geological formations, in reference to 

 some remarks by Mr. Jenkins " On Strata Identified by Organic 

 Remains," printed in the previous number. Mr. Jenkins had stated 

 that in his anniversary address to the Geological Society for 1863, 

 Prof. Ramsay had denied a recurrent fauna in the Silurian, Devonian, 

 and Carboniferous formations of England and America ; while in his 

 address for 1864 he had acknowledged a recurrent fauna in the 

 Lower Oolite. In reply to this. Prof. Ramsay states that by the 

 fauna of a province or formation is meant its collective species, not a 

 small per-centage of them. In the case mentioned, that forms 

 living during the Inferior Oolite period had migrated during the 

 Fuller's earth sea, and retiirned when the Grreat Oolite was being 

 deposited. Only about eighteen or twenty per cent, of the Inferior 

 Oolite species were recurrent. Prof. Ramsay adds that the Oolitic 

 sub-divisions ought not to be compared with the great Silurian, 

 Devonian, and Carboniferous series, each of which contains several 

 groups of formations, some of which are comparable to the whole 

 British series of Oolites together. 



III. — Reliquiae Aquitanic^ : being Contributions to the Arche- 

 ology AND PALiEONTOLOGY OF PeRIGORD AND THE ADJOINING 



Provinces of Southern France. By Edouard Lartet and 

 Henry Christy. Part I. December 1865. 4to., pp. 16, and 6 

 plates. London : H. Bailliere. 



IT is with a somewhat melancholy pleasure that we look on the 

 first part of this extremely interesting work, which presents to 

 us some of the results of a new Anglo-French Alliance, as full of 

 promise for science as any ever contracted. It is sad to think that 

 our countryman (Mr. Henry Christy) should not have lived to see 

 the record of his persevering labour published ; but death cut short 

 his useful career on the 4th May, 1865.^ 



We are glad to learn that M. Lartet intends to persevere in 

 carrying out, as far as psssible, the original intentions of Mr Christy 

 regarding this book; and that M. Penguilly I'Haridon, Mr. John 

 Evans, F.R.S., Mr. A. W. Franks, Dir. S.A., Mr. W. Tipping, F.S.A., 

 and Professor T, Rupert Jones, F.G.S., have promised their assist- 

 ance : that the last-named gentleman will edit the work, and finally 

 that Mr. Henry Christy's brothers are resolved to give every assist- 

 ance in producing the book in the style he had contemplated.
